Lady Gaga is facing criticism after showing off a fuller physique while performing in Las Vegas Saturday. At the MGM Grand Garden Arena, the 28-year-old filled out her costumes, and showed off a much curvier figure than the one she had when she first became famous in 2008.

While donning a number of different outfits for her performance, Gaga looked bit wider than she has in the past, causing some fans to comment negatively. “This isn’t sexy, this is FAT,” wrote @gagatuvoz. “Gaga is over, she is fat, katy [perry][is] better than her,” wrote @boraabora.

This certainly is not the first time Gaga has been fat-shamed. In 2012, the media criticized the singer after she gained 25 pounds. In response, she started a body revolution, inspiring little monsters all over the globe to be brave and accept their bodies, regardless of excess weight, scars and other "imperfections."

"Today I join the BODY REVOLUTION. To Inspire Bravery. And BREED some m$therf**king COMPASSION,” Gaga wrote on her official website, after posting pictures of herself in a bra and underwear. "This profile is an extension of that dream. Be brave and celebrate with us your 'perceived flaws,' as society tells us. May we make our flaws famous, and thus redefine the heinous,” Lady Gaga added.

Gaga will most likely not be phased by this most recent attack on her weight. In 2012, she noted boyfriend Taylor Kinney, who has appeared in a number of her music videos, has given her fuller figure his stamp of approval.

“My boyfriend prefers me curvier,” she wrote. “I'm happy. Happier than I've ever been. I am not going to go on a psycho-spree because of scrutiny. This is who I am. And I am proud at any size.”
